Implement C11 excess precision semantics for conversions (PR c/82071).
C11 semantics for excess precision (from N1531) are that an implicit
conversion (from the usual arithmetic conversions, not by assignment)
from integer to floating point has a result in the corresponding
evaluation format of that floating-point type, so possibly with excess
precision (whereas a cast or conversion by assignment from integer to
floating point must produce a value without excess range or precision,
as always). This patch makes GCC support those semantics if
flag_isoc11 (which in turn means that conditional expressions need to
support generating a result with excess precision even if neither
operand had excess precision).
C99 is less than entirely clear in this regard, but my reading as
outlined at <https://gcc.gnu.org/ml/gcc-patches/2008-11/msg00105.html>
is that the results of conversions from integer to floating-point
types are always expected to be representable in the target type
without excess precision, and this patch conservatively keeps these
semantics for pre-C11 (i.e. if an older standard is explicitly
selected).
Bootstrapped with no regressions on x86_64-pc-linux-gnu.

Add comments to struct cgraph_thunk_info
This commit adds comments to fields in the cgraph_thunk_info structure
declaration from cgraph.h. They will hopefully answer questions that
people like myself can ask while discovering the thunk machinery. I
also made an assertion stricter in cgraph_node::create_thunk.
Bootsrapped and regtested on x86_64-linux.

[include] Add macro DISABLE_COPY_AND_ASSIGN
We have many classes that copy cotr and assignment operator are deleted
in different projects, gcc, gdb and gold. So this patch adds a macro
to do this, and replace these existing mechanical code with macro
DISABLE_COPY_AND_ASSIGN.
The patch was posted in gdb-patches,
https://sourceware.org/ml/gdb-patches/2017-07/msg00254.html but we
think it is better to put this macro in include/ansidecl.h so that
other projects can use it too.

Turn TRULY_NOOP_TRUNCATION into a hook
I'm not sure the documentation is correct that outprec is always less
than inprec, and each non-default implementation tested for the case
in which it wasn't, but the patch leaves it as-is.
The SH port had a couple of TRULY_NOOP_TRUNCATION tests that were left
over from the old shmedia port.
